Thats…not how nuclear arms work.
Isn’t the smallest effective nuke the Davy Crocket? Pretty sure it’s warhead is still the size of a large hardcase suitcase.
Isn’t that from the 1950s? Maybe top secret tech has progressed since then.
It’s from the 50s but as I understand it nukes as we have them now require certain physical properties and dimensions to work with that being about as small as you can get. Anything smaller and the reaction either fizzles out, you get a dirty bomb, or the explosive yield is worse than traditional explosives of equivalent size. To make it any smaller you’d need a fusion bomb most likely.
Wouldn’t you still need a fission bomb, to initiate the fusion reaction?
Probably, though as I noted the problem with such small nuclear arms isn’t their capacity but moreso their efficiency and consistency. A fusion bomb could help to amplify at least the capacity for destruction, assuming it can’t be circumnavigated through some technological fuckery, frankly I don’t think anyone can comment on fusion bombs with any degree of accuracy given that we haven’t figured out sustained fusion reactors.
You need a critical mass of material to initiate an explosion. So there is a limit to how small you can get with them. That critical mass in not including all of the other gear they need attached to get it to explode.
